Прогнозирование эффективных режимов работы лифт-реактора каталитического крекинга с применением метода математического моделирования

Abstract

Today the most intensive and commonly used catalytic cracking process in crude oil refining is continuous fluid catalytic cracking FCC. Riser reactor and regenerator are the most complex and crucial parts of any FCC unit because of intricate multiphase flow behavior coupled with complex chemical reactions. Development of highly effective catalysts along with recent catalytic cracking technology enhancements made it possible to reduce contact time of products and catalyst, improved separation of products and catalyst, and simultaneously improving desirable products yields and quality. This paper presents catalytic cracking feedstock and products analysis results. Density, molecular weight and sulfur mass content of studied samples was established. To increase the desirable products yield It is necessary to maintain specific temperature: for diesel - 503-510 °C, for gasoline - 524-529 °C, for unsaturated gas - 528-537°C. It was assumed on the basis of mathematical model calculations presented in this paper.
